DIRIGIBLE AIR-SHIP.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed May 6, 1904. Serial No. 206,608.

To all whom it may concern:

Be it known that I, ,HIPPOLYTE LOUIS MALnoo'r, a citizen of the Republic of France,-

and a resident of Paris, No.. 65 Faubourg dn Temple, in France, have invented'certain new and useful Improvements in Dirigible Air-Ships, of which the following is a speci fication. This invention relates to an. improved dirigible air-ship built on thefl principle of. the combination of the balloon and aeroplane and combining the principles of apparatus lighter than air with those of apparatus heavier th an air.

'15 The apparatus imitates very closely the flight of a bird, while having at the same time a certain analogy witha kite.

The combination of the balloon with the aero lane approximately equilibrates the weig t of the apparatus, so that the motor used for propulsion need not sup ort the air ship in the air; the work done y the said motor-Sis thus exclusively employed for displacing the air-ship.

One form of the invention is illustrated as an example in the annexed drawings in'which Figure 1 is an elevation of the air ship; Fig. 2 a plan view thereof with the balloon removed, Fig. 3 a front view, Fig. 4 a cross section on the line 44 of Fig. 1 and Fi 5 a partial longitudinal section of one o the Wings.

-The apparatus comprises a double balloon, the two parts 6 and 7 of which are placed end to end and have the same longitudinal axis. The rear balloon part F tapers towards its rear end and its lower rear part, which serves as a wind cutter, is shaped in cross-section approximately like the corresponding part or stern of a ship. In the same manner the lower front part tapers like the bow of a'ship. The lines 8 in Fig. 3 indicate the shape in both cases. The central parts of both balloons are cylindrical. j From the balloon is sus ended a trussed frame or keel 9 by which. 0 e rigidity ofthe air-ship is secures. vThe'central part of the said frameis ofrectangular section and contains whatf'may be called a cabin or well 10 l for the 1pilot or aeronaut and the motor man.

e central part to the ends the frame.

From t is of triangular section, the apex of the triangle pointing downwards, so that the under.

art of the frame forms for almost its entire ength, a lon 'tudinal edge (Figs.3 and 4). At the rear, t e'lframe termlnatesin' a point.

point, like the frame 9 (Fig; 2).

adapted to lift the aeroplane, comprising the The triangular parts of the frame are covered with light material in order to be adapted-to cut through'the air. The well 10, contains a motor.11, referably of the .explosionntype' o which is a apted to drive by means of varrable speed'gear, two transverse shafts 12 and 12, each of which has at its outer end a bevel gear wheel 13 meshing with a similar wheel '14. 'Theaxle of each wheel 14 carries a proeller 15 and is mounted in alight support or caring 16 fixed to the frame 9 and having its outer end-connected-to the latter by means of stays 17 adapted to strengthen the structure. The ropellers are arranged below that point 7 at w ich the'tapering endsof the balloons 6 and 7 meet, so that the latter do not interfere with the rotation ofthe propellers.

- At the sidesof the frame 9' wmgsf18, 18, and 19, 19 are fixed in such a manner that a 7 space between the 'two wings 18 and 19 on. each side is left for the respective propellers- 15. The wings 18 terminate'at the rear in a The wings consist of light frames -20.fixed to the frame 9 0 and connected to the latter at intervals by means of stays 21 (Figs. 3 and 4) in order to insure rigidity.- Between-the frames 20 and the frame Qbands 22 of light material such as silk I are stretched in slightly incline'd'plane's 35 (Fig. 5.) in such a manner that they overlap each other but have a .certain amount 'of space between them.

' Below the frame 9 and at equal-distances- .from the center thereof are mounted two grooved pulleys 23 23 over which passes a rope 24 supporting a car or the like 25 adapt-- ed to contain ballast, baggage or passengers. The rope 24 is connectedto a winch-drum 26 arranged in the well 10. Across eachballoon 6 and 7 is stretched a-gas'ti'ght diaphragm 27 so that in the lower part of the balloon there is produced a separate chamber 28, which is adapted to communicate with the outer atmosphere by means of valves 29. Tubes 30 provided with valves 31 lead from the lower parts of the chambers 28 to an airpump or fan operated by the motor 11-.

The lifting power of the-balloons 6 and 7- is frame 9, the wings 18 and 19, the propellers 15 and accessories such as the motor, winch and the like, butLis insufficient to lift' the car 25 and its contents, a suitable predeter-' mined margin or over-weight being calcu- 1 10 latedin advance. When the air ship starts the apparatus lighter than air ascends and paying out cable to the rear.

insures the equilibrium, stability and fixityof the center of gravity which are the essen-' tial conditions for aerial navigation. I

For turning the ship, the propeller mech-v 1 anism is so operated that one propeller re finds its naturalpoint of equilibrium a certain distance above the ground, only the car remaining in contact with the latter; The aeronaut then operates the winch 26 in such a manner as to pay out rope towards.

the front of the air-ship, whereupon the rear part of the latter is pulled downwards by the weight of the car and the air ship assumes an inclined position. The motor is then caused to revolve the propellers 15 and the reaction at the air driven by the latter against the wings l8 and 19 causes the air-ship to ascend in an inclined direction with the car 25. hen the aeronaut desires to discontinue the ascent he pays out rope towards the rear by means of the winch 26 until the air-' ship assumes a horizontal posltlon and travels in a horizontal direction. Thede scent is effected by reversing the conditions which produce the ascent, that is to say by The car thus remains unchanged and their lifting power constant. Safety-valves are, how-' ever, provided the upper parts of-the bal loons for use in case otexcessive ex ansion of the gas. Itmust'be'mentioned t at this arrangement is indispensable to the air-ship since the difierence' between the lifting power of the balloons and the-total weight of the apparatus must remain constant, the

power of the motor'being limited and serving only for the propulsion of the ship. It is obvious that if. this difference were to crease substantiallyln such a'manner as to establish too great apreponderance of weight, the apparatus would not work.

Having now particularly described and ascertained the nature'of my said invention. P3

and in what manner the same is to be formedl declare that ,what I claim is:

In a flying machine', the combination with a balloon, of a longitudinal beam arranged under said balloon'and connected with the same by means of cables, plates arranged longitudinally. on each side of 'said. beam and composed of light materialto form an acre plane, two 'ropellers arranged one on each side of the alloon, a winch-located under said balloon, a cable wound upon said winch and passing over two pulleys arranged under said beam and at equal distances from the center of its length, a ballast car-mounted and movable upon said cable, and means for actuating the said propellers, the. whole ar ranged substantially as described and for the object specified. In testimony whereof I have signed my name to this specifi-oationin the presence of two subscribing Witnesses. I
